Bluetooth Not Working in iOS 11 on iPhone?
Please use the latest iOS 11.0.2 release
Here’s How to Fix it
Like in case of any major iOS software update this time also some users seem to have problems after updating (OTA) to iOS 11 such as Wi-Fi / Bluetooth connection problems, draining battery life a lot faster etc.
Some users seem to be having problems connecting their iPhones and iPads to Bluetooth devices (iBlue Smart Gate) after installing the iOS 11 update.
For the very first step, please take it into consideration, that the problem is actually based on your iPhone or iPad and not on the Bluetooth accessory (iBlue Smart Gate /Smart Key) you’re trying to connect to.
How to Fix iOS 11 Bluetooth Problems
After you have considered that the problem lies in you iPhone or iPad running iOS 11, here are a few solutions you could try:
1. Turn off Bluetooth and Reboot
The first thing to try is to turn off your Bluetooth and restart your iPhone or iPad:
•Turn off Bluetooth by going to Settings > Bluetooth and turning off the Bluetooth toggle.
• Hard reset your iPhone by holding the Home button (Volume down button on iPhone 7, iPhone 7 Plus, iPhone 8 and iPhone 8 Plus) and the Power button until you see the Apple logo.
• Now enable Bluetooth again from Control Center or Settings > Bluetooth.
• Try connecting to the device now. If the problem still isn’t solved, try the next solution.
2. Reset Network Settings
If the first tip did not work, you could also try resetting your network settings. A side effect of doing this is that all your Wi-Fi settings will also be cleared, so you might have to rejoin Wi-Fi networks, and configure VPN all over again.
Here’s how to reset network settings:
•Open Settings and navigate to General > Reset
• Tap Reset Network Settings
• You’ll be required to enter your passcode, if you have one.
• Confirm your action in the popup
3. Restore and Setup as new iPhone
This is not ideal, but if none of these tips fix your issues, the last resort is to restore your iPhone or iPad via iTunes, and set it up as a new device. This way, you start afresh, and get rid of possibly problematic customizations and settings on your device.
Open iTunes on your Mac or PC. If you can’t access a computer and your device still works, you can erase and restore your device without a computer.
Connect your iPhone, iPad, or iPod to your computer with the cable that came with your device.
If a message asks for your device passcode or to Trust This Computer, follow the onscreen steps. If you forgot your passcode, get help.
In the Summary panel, click Restore [device].
Click Restore again to confirm. Then iTunes erases your device and installs the latest iOS or iPod software.
After your device restores to factory settings, it restarts. Now you can set it up as new.
